2014 BA3 Goldstone Radar Observations Planning


Background


2014 BA3 was discovered by the Mt. Lemmon Survey (Arizona) on January 21, 2014.
It has an absolute magnitude of 28.3 suggesting a diameter within a factor of two
of only 7 meters, but nothing else is known about its physical properties.
This object is one of the best candidates ever discovered for NASA's new Asteroid Robotic
Retrieval Mission, so we will try to detect echoes at Goldstone to improve the asteroid's
orbit and to characterize its physical properties.  

The monostatic signal-to-noise ratios will be weak and we cannot guarantee that we 
will detect echoes, so we will also receive at the Green Bank Telescope in order to 
increase the SNRs by about a factor of three.   Arecibo is offline due to damage experienced
during an earthquake on 2014 January 13, so Goldstone provides our only chance to
observe this asteroid with radar.

2014 BA3 will approach within 0.0151 AU on January 26.   This object is at about 20th 
magnitude so it is a difficult target for observers using optical telescopes.

Update: Observations at Green Bank on Jan. 28 have been cancelled.  Monostatic observations
that day will go forward.

This object is on NASA's "NHATS" list of potential human mission targets.  As a result, physical
observations are particularly important.

Uncertainties

From Jon Giorgini, 2014 Jan. 27:

Nine new optical measurements were reported last night. Now with
49 total (Jan 21-26), orbit solution #11 was estimated. DSS-14 predict

From Jon Giorgini, 2014 Jan. 26:

Based on 40 optical measurements (Jan 21-25), 2014 BA3 orbit
solution #9 was estimated. OSOD set-up on aardvark has been
updated.

Setups



We don't know anything about the spin state of 2004 BA3, but if it's similar
to other tiny asteroids, it could have a rapid rotation period in the realm of
only ten minutes.  If so, then the bandwidth could be roughly 4 Hz.
